Rob,
Would you mind to elaborate further on this? I am a little concerned that
my understanding (nodetool repair is *not* the only way one can achieve
consistency) is not correct. I understand that if people use CL < QUORUM,
nodetool repair is the only way to go, but I just cannot see how can that
be the only way irrespective of everything else.
Thanks in advance for your input!
